Pennisetum setaceum, commonly known as fountain grass, is a perennial grass native to Africa and the Mediterranean region. It is characterized by its arching, slender leaves and fluffy flower spikes that resemble fountains, which can reach heights of 3 to 5 feet. This grass thrives in warm climates and is often used in landscaping for its ornamental value. Fountain grass prefers well-drained soils and full sun, making it suitable for gardens, borders, and erosion control. However, it can become invasive in some areas, outcompeting native plants. Proper management is essential to prevent its spread in non-native habitats.
